MAIL-IBAOX CARRIER.

' SPECIFICATION forming part of Letters Patent NO. 722,929, dated March 17, 1903.

Application iiledMay 12,1902. Serial No. 106,936. (No modal.)

To all whom it may concern.-

. Be it knownthat I, ISAAC UNGER, a citizen of the United States, residing at Greenville, in the county of Darke and State of Ohio, have invented a new and 'useful Mail-Box Carrier, of which the following is a specification.

This invention is intended for use more particularly in connection with the rural free-mail-delivery system where the house to which the mail is addressed is distant from the road to enable the residents to convey the mail to and from a point of delivery at the line of the road, and thus obviate the necessity for the mail-carrier leaving his route in delivering, or receiving the mail.

The device may also be employed for conveying other matter than mail and .for other purposes than in connection with the rural free-delivery system, but is more particularly designed for the purposes above indicated.

In the drawings illustrative of the invention, Figure 1 is a side elevation with the central portions broken out to economize space. Fig. 2 is an enlarged'detail of the carrier-receptacle at one of the intermediate supporting-posts. Fig. 3 represents an enlarged sectional view of the standard to which the cable ends are attached. Fig. 4 represents another sectional view thereof, showing the cable-carrying drum mounted thereon. Fig. 5 represents a plan view of I a portion of the carrier, showing the mail-receptacle in position near the supporting-pulleys. Fig. 6 represents a detail view showing the means for locking the drum against backward movement. 7

The device may be erected between comparatively distant points, and in the illus-' tration shown in Fig. 1 the terminals are represented at 10 and 11, respectively, the former indicating the point where the mail is to be delivered, such as the residence to which the mail is addressed, and the latter the point on the mail-route where the carrier deposits the mail. The terminals will be connected by a guide or trolley wire '12, which is supported at suitable intermediate points by posts 13, having U-shaped hangers Mengaging the guide wire, as shown. At the residence end a cable-pulley 15 is connected, as

by a bracket 15*, and at the deposit end another similar pulley 16 is similarly supported by a bracket 16, the bracket in the latter case being preferably carried by a vertical bar 17 upon a post 18. Over the pulleys 15 16 a cable 19 is carried, as shown, the adjacent ends of the cable being united to a standard 20. This standard 20 is bifurcated at its lower end, and the membersthereof curve outwardly in opposite directions, as' at 20 20", and are pro- 'vided with grooves to receive the adjacent ends of thecable, which are carried upward through openings in the standard and engaged to a drum 21 upon the standard, as shown. The grooved bifurcated lowerend of the standard holds the cable ends out of contact with each other and prevents friction. The upper end of this standard 20 is also bifurcated, and the two members 20 and 20 are spaced apart and otfset to form bearing for the drum 21. The drum 21 will be provided with a ratchet '22, with which a pawl 23 on the standard 20 engages. The shaft 21, on which the drum is mounted, is extended through the arm 20 in the form of an angular stem '21" for engagement by a suitable tool or handle for rotating the drum and regulating the tension of the cable. By this simple means the cable may be stretched to any required extent and maintained at any desired tension by merely revolving the drum 2].

Attached to the standard 20 is a laterallyextended frame 24, carrying traveler pulleys or trolleys 2525, which engage the trolleywire 12, as shown. The mail-receptacle is suspended from this frame 24, the receptacle being indicated at 26 and connected to the frame by reversely-diagonal hanger-bars 27 27 referabl curvin inward, as shown so that the center of gravity of the receptacle will be in substantial vertical alinemen-t with the trolley-wire to obviate side strains. 1

by side, as indicated, without danger of the side draft causing them to f ride the pulleys and run otf from them. The pulley 1 5 will be provided with a'crank 15 or other means by which the cable 19 may be operated. By this simple means the mail maybe conveyed to and from the route of the mailcarrier any desired distance and the work of the carrier thereby greatly lessened, as by this simple device there will be no necessity for him to take time to leave the route to deliver mail to distant residences.

The cable 19 may be of any size to adaptit to the distance traveled and may be either one strand of wire or several strands twisted into a cable or formed of any other suitable material.

The device may irregularity of the ground over which it is carried and may bemodified and altered in minor particulars without departing from the spirit of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim is 1 1. In a device of the class described, a trolle'y-wire supported between terminals, cablepulleys disposed at said terminals, a trolley with wheels engaging'said trolley-Wire, a cable engaging said pulleys, and a single drum ported from said standard and engaging said trolley-wire,

substantially as described. 3. In a device of the character described, a

trolley-wire supported between terminals, ca-- 4 ble-pulleys disposed at said terminals, a cable engaging said pulleys, a standard having bifurcated upper an lower ends, the upper ends being spaced apart and ofiset, a drum mounted between said offset ends and conbe readily adapted-to anynected with the ends of the cable, means for revolving the drum, and trolley-wheels carried by said standard for engaging the trolto receive the ends of said cable, means for revolving said drum, and means for locking said drum from backward movement, substantially as described.

5. In a device of the character described, a trolley-wire supported between terminals, cable pulleys disposed at said terminals, a standard having grooved diverging lower portion adapted to receive the ends of said cable, means carried by said standard for adjusting the tension of said cable, and trolley-wheels carried by saidstandard and engaging said trolley-wire, substantially as described.

6; In acarrier having a cable guided over terminal end pulleys, means for connecting the ends 'of' said cable consisting of' a vertically-perforated standard bifurcated to form curved guides for the cable ends, means for securing, upon the latter. g

7'. In a device of the character described, a cableguided over pulleys at""the terminal ends, means for connecting the ends of, and adjusting the strain upon" the cable, a'carrier, means for supporting said carrier, and

and having and adjusting the strain connecting means between said carrier and the device connecting the ends of the cable. I

In testimony that I claim the foregoing as my own I have'hereto affixed my signature in the presence of two Witnesses.
